ING MACHINE.

SPECIFICATION forming part of Letters Patent No. 758,502, dated April26, 1904.

Application filed July 29, 1903.

To all whom it non/y concern: I Be it known that I, HENRY BAKER BLACKINTON, a citizen of the United States, residing at Auburn, in the countyof Androscoggin, State of Maine, have invented certain new and usefulImprovements in Box-Covering Machines; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same. My invention relates to improvements inpaper-box-covering machines. It is designed to cover the outside wall, aportion of the bottom, and a portion of the inside with a single stripof paper. So far as I am aware, it has been customary hitherto for thebox-maker to turn the edge of the paper under the bottom and to strikeit down inside the box by hand. The object of my invention is to providemeans for automatically and mechanically performing the whole operation.

It also relates to improved means for delivering the paper to the box.

In the drawings herewith accompanying and making a part of thisapplication, Figure 1 is a side elevation of the feeding mechanism,showing its position relative to theblock upon which the box is placedpreparatory to being covered. Fig. 2 is a side elevation of thebox-covering mechanism. Fig. 3 is a plan view of the feeding andcovering mechanism,

showing thetwo assembled, some of the parts being omitted for the sakeof clearness. Fig. 1 is a perspective view of the paper-feeding carrier,and Fig. 5 is a per spective view of the cam for elevating thereciprocating side and bottom rubber mechanism.

Same characters of reference refer to like parts.

In said drawings, 1 is a suitable frame for supporting the feedingmechanism. On abracket 2 is rotatably mounteda roll of'paper 3. Thepaper, which should be somewhat wider than theheight of the box to becovered, passes from the paper-roll, between rolls tand 5,0ver apaster-roll 6, suspended in a glue-tank 7 It thence passes betweentension rolls or bars 8 and 9, thence around a rolllO, thence in SerialNo. 167,383. (No nodel.)

contact with a guiding-apron 11, and thence over a roll 12. It thencepasses into the feeding-carriage between the base 13 and aswingingclamping-jaw 14, pivotally mounted on a bearing 15, the clamping-jawbeing held in yielding tension against the paper by means of acoil-spring 16. The paper extends a short distance beyond the deliveringend of the carriage and is supported at each edge by fingers 17,extending forwardly from the carriage in order to enable the box-makerto adjust the end of the paper upon the box B. The paper-carrier has areciprocating motion imparted to it by means of a hand-lever 18, throughintermediate links and levers 19, 20, 21, and 22, the link 22 being.pivotally connected with ashaft 23, to which the carriage is attached.The hand-lever 18 also raises and lowers a calendering-roll 24, adaptedto bILV erse the box while being covered, said handlever operating forthis purpose through intermediate links and levers 19, 20, 25, 26,

maker moves the lever 18 to advance the carriage to the box it raisesthe calendering-roll from the box. A pivoted knife 28, operated by afoot-lever 29 and operating in conjunction with a second knife 30,severs the paper as the box is covered. The box to be covered is placedupon a rotatable block A of substantially the same size and shape as thebox to be covered, but allowing the edges of the box to project slightlybeyond the block. The box when placed in position on the block is heldfirmly thereto by means of a clamp 31, pivotally mounted upon aprojection 32 upon the frame 1. This can be brought into position byhand or by a foot-lever 33.

1 wish it understood that the particular method of feeding the paper tothe box is not essential to the leading feature of the invention, whichconsists in means for applying the paper to the box so that theparticular mechanism for feeding the paper may be varied at will. Thepaper may even be drawn by hand over the pasting-rolls and applied tothe box.

I now pass to a description of the mechanism which applies the paper tothe box after it is delivered thereto by the paper-f :eding and 27, allarranged so that when the boxmechanism heretofore described. The blockupon which the box is placed while being covcred is secured to androtates with a shaft 34, mounted in bearings 35 and 36 by means of agear 37, meshing with a pinion 38 on a shaft 39, shaft 39 being rotatedby means of a loose pulley 40, driven by a power-belt. (Not shown.) Theoperator causes the shaft which carries the block to rotate by pressingagainst a lever 41, carrying a clutch 42, which presses the loose pulleyagainst a friction-disk 66, rigidly mounted on shaft 39. This enablesthe operator to rotate the block as desired. The mechanism for rubbingthe paper upon the sides of the box and around upon the bottom consistsof a reciprocating shaft 43, one end being eccentrically connected withthe crankwheel 44, driven by a belt, (not shown) and the other endprovided with a rubber-carrying frame 45, slidably mounted thereon. Therubber-frame is provided with rubbing-rollers 46 or any convenientrubbing device. Pivotally connected with said frame is an auxiliaryframe 47, adapted to project slightly beyond the bottom of the box atthe extreme reciprocation of the rubber-carrying frame. Said auxiliaryframe has pivotally-secured thereto a rubber 48, which pushes the paperdown upon the bottom of the box and causes it to adhere thereto. Theauxiliary frame is held down upon the box at all times with yieldingtension by means of a spring 49. The reciprocating shaft 43 and itsrubbing mechanism can be raised above the box by means of a camlever 50,pivoted upon a post 51. It can also have vertical adjustment by beingslidably mounted in a slotted post 52.

The mechanism for striking the edges of the paper down inside of theboxconsists of four sets of spring-controlled rollers, two sets ofsubstantially the same length as the box oppositely positioned and twosets of substantially the same width as the box oppositely positioned.These rollers are mounted upon one of the blades of a forked frame 53,pivotally secured to a shaft 54 or to an offset 55 on said shaft. Theother end of the fork is provided with a cam-roll 56, operating in azigzag campath 57. Shaft 54 is adapted to have a reciprocating motion inbearings 58, rigidly mounted upon shaft 34. Shaft 54 is given areciprocating motion by means of a cam-101159 traveling against acam-surface 60 and a backward reciprocation traveling against acam-surface 61. The forward movement serves to bring the rolls 62 63into engagement with the projecting edge of the paper, the roll 62 onthe outside and the roll 63 on the inside of the box turning the paperas it descends toward the box and striking it round the edge and againstthe inside thereof. The backward reciprocation of the shaft 54 withdrawsthe roll from engagement with the box. The rolls 62 and 63 are heldtogether with a yielding tension by means of springs 64 pressing againstarms 65, in which the rolls are pivotally mounted. I have described theoperation of one set of these rolls and wish it to be understood thateach of the sets is constructed and operated in the same manner.

The operation of my improved machine is as follows: The paper havingbeen placed by hand in position in the carriage, the hand-lever drawsthe carriage forward until the free end of the paper is deposited uponthe side of the box, as seen in Fig. 1. The shaft which carries theblock is then brought into operation, the box rotating toward theoperator, drawing the paper over the box as it rotates with the block.The rubbingroller first smooths the paper out on the sides of the boxand is followed by the reciprocating rubber and the bottom-turningrubber. As the box rotates after one side is completely covered, thestriking-in rolls take position, turning the projecting edge of thepaper down inside the box and pressing it closely against it and causingit to adhere thereto.

The construction of the several parts of my improved box-coveringmachine and means for operating them can be varied in many ways andstill come within the spirit and scope of my invention.

Having thus described my invention and its use, 1 claim 1.
